# Hemi vs Audio Frequency Converter

The clearest difference is price: Hemi at Free against Audio Frequency Converter's $8.99. Hemi also leads on rating (4.4 vs 3.7) and ratings volume (2.5K vs 11). Audio Frequency Converter's advantage is in-app purchases (none vs 2) and chart position (#186 vs unranked). On ads there is nothing between them.

Hemi is free to download; Audio Frequency Converter costs $8.99 up front. Hemi sells 2 in-app purchases, starting at $14.99 per month. Audio Frequency Converter asks for nothing beyond the download.

Hemi holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Hemi has 2.5K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 32% of Hemi's written reviews are positive against 43% of Audio Frequency Converter's, so the app with the better star average is not the one people write more warmly about.
